Gavin Williams (RHP): 74% NRFI, 3.98 ERA, 1.12 WHIP, 11.8 K/9, 2.8 BB/9. First pitch 6:40 PM ET at Progressive Field (660 ft).* Spencer Miles is the reason to look here, a 100% scoreless rate in the first that carries most of the weight for this lean. Gavin Williams is the softer side at 74% NRFI, but he only has to be ordinary in the first for this to cash. Spencer Miles's 2.3 BB/9 means the leadoff man rarely reaches, and empty bases in the first almost always mean a zero. The lean is NRFI, carried by the stronger arm. ## San Francisco Giants at Pittsburgh Pirates *Logan Webb (RHP): 83% NRFI, 3.72 ERA, 1.10 WHIP, 7.2 K/9, 2.2 BB/9, NRFI streak of 6. Paul Skenes (RHP): 74% NRFI, 3.79 ERA, 1.12 WHIP, 10.9 K/9, 2.5 BB/9, NRFI streak of 4. First pitch 6:40 PM ET at PNC Park (730 ft).* Neither starter hands out early traffic, and in the first inning that is most of the battle. Logan Webb runs a 2.2 BB/9 and Paul Skenes a 2.5 BB/9, so a walk is unlikely to spark the run this bet is fading. Paul Skenes is the softer side at 74% NRFI, but he only has to be ordinary in the first for this to cash. Logan Webb is trending up as well, a 2.87 ERA across his last five starts against a 3.72 season mark. The lean is NRFI, carried by the stronger arm. > **Want the full board?** See all of today's plays on [Top Plays](/top-plays), or go deeper on the [NRFI dashboard](/mlb/nrfi). ## Seattle Mariners at Boston Red Sox *Bryan Woo (RHP): 80% NRFI, 4.36 ERA, 1.10 WHIP, 9.0 K/9, 1.9 BB/9. Jedixson Paez (RHP): 0% NRFI, 18.00 ERA, 2.33 WHIP, 0.0 K/9, 9.0 BB/9. First pitch 6:45 PM ET at Fenway Park (20 ft).* Bryan Woo anchors this one at 80% NRFI, and the combined 58% rate keeps the game in play as a lean. Jedixson Paez is the concern here with a 0% NRFI rate in his sample, the model regresses that toward the league mean, but the raw results flag early-inning vulnerability. The bet leans on the stronger arm holding the line. Bryan Woo's 1.9 BB/9 means the leadoff man rarely reaches, and empty bases in the first almost always mean a zero. Jedixson Paez's 0% NRFI rate across 0 starts is worth noting, the model applies shrinkage, but the raw results suggest caution on this side. NRFI is the side, with a touch of caution. ## Honorable Mentions - **San Diego Padres at Cincinnati Reds:** Randy Vásquez riding a run of 6 scoreless first innings. - **Philadelphia Phillies at Arizona Diamondbacks:** Jesús Luzardo sitting at 93% NRFI. - **New York Yankees at Los Angeles Angels:** Gerrit Cole riding a run of 9 scoreless first innings. ## Games to Avoid These matchups carry the highest first inning scoring risk on tonight's slate. **Detroit Tigers at Minnesota Twins.** Andrew Morris is the weak link at 50% NRFI, and the combined 36% rate sits near the bottom of the slate. Leave this one alone. **Baltimore Orioles at Colorado Rockies.** Coors does what Coors does. At 5,200 feet the ball carries, and even the better arm here gives back margin in the first. Leave this one alone. **St. Louis Cardinals at Los Angeles Dodgers.** Eric Lauer is the weak link at 53% NRFI, and the combined 41% rate sits near the bottom of the slate. We are passing here. ## Related Guides - [How to Use the NRFI Dashboard](/blog/how-to-use-nrfi-dashboard) - [MLB Weather Betting Guide](/blog/mlb-weather-betting-guide) - [MLB Stats Explained](/blog/mlb-stats-explained) ## Before You Lock Confirm the starting pitchers on the [NRFI dashboard](/mlb/nrfi). A bullpen game kills NRFI value immediately. Check the weather at first pitch and be careful at altitude, Coors in particular. NRFI bets land 55% to 65% of the time historically, and you need roughly 52.4% to break even at minus 110 odds.
